15 Open Grants for Small Ocean Conservation Nonprofits in the U.S. in 2026

Finding grants for ocean conservation sounds simple until you actually start opening the applications.

One fund supports the environment, but only in three counties. Another funds conservation, but wants a project budget larger than your organization's annual revenue. Then you find an absolutely beautiful marine grant and realize the deadline was four months ago.

So this list starts with the useful question: which grants are actually open right now, and which ones can a smaller nonprofit realistically pursue?

These opportunities were still open as of September 18, 2026. Some are directly about oceans and marine wildlife. Others fund coastal habitat, watersheds, water quality, restoration, and community stewardship.

If your organization is small enough to file Form 990-N, uses a fiscal sponsor, or is still building its first serious grant history, there are options here worth looking at. Just check the financial-document requirements before putting hours into a proposal. Some funders are built around grassroots organizations. Others accept small nonprofits but expect more developed budgets, partnerships, permits, or project plans.

1. The Lawrence Foundation

Deadline: October 31, 2026
Typical grant: $5,000 to $10,000

Official Lawrence Foundation application page

The Lawrence Foundation funds U.S.-based 501(c)(3) public charities working in areas that include the environment. It does not impose geographic restrictions on where the environmental work itself takes place, provided the applicant is a qualified U.S.-based charitable organization. Fiscal sponsorship is also allowed.

Applications are relatively straightforward. The foundation asks for organizational information, a description of the funding need, tax-exempt status, and the amount requested rather than beginning with a separate letter of inquiry.

For an ocean nonprofit, this could cover a range of environmental projects, but I would make the conservation result very clear. Coastal restoration, pollution reduction, habitat protection, marine stewardship, or another measurable environmental project gives the proposal considerably more substance than broad awareness alone.

2. Fund for Wild Nature

Deadline: October 1, 2026

Official Fund for Wild Nature grant guidelines

Fund for Wild Nature is worth reading if your organization does advocacy or campaign-based conservation work.

It funds North American campaigns protecting native species, wild ecosystems, wilderness, habitat, and biodiversity. Examples include advocacy, litigation, public policy, and similar direct conservation efforts. It does not fund basic scientific research, wildlife rehabilitation facilities, ordinary habitat-restoration projects, conferences, or organizations receiving government funding.

That means this is not the grant for every marine nonprofit.

It becomes much more relevant if you are working to stop a threat to a coastal ecosystem, protect marine habitat, defend a species, influence conservation policy, or organize a focused biodiversity campaign.

Applicants first complete an eligibility quiz before proceeding to the application.

3. The Pollination Project

Deadline: Rolling
Grant: Up to $500

Apply to The Pollination Project

This is one of the most accessible opportunities on the list for a genuinely tiny organization.

The Pollination Project funds individuals, informal groups, and registered nonprofits around the world. The organization's annual budget must be below $50,000, the proposed project's total cost must be below $10,000, and organizations cannot have paid staff, although occasional contractors for professional services are allowed.

Five hundred dollars will not restore a coastline.

It can, however, buy field supplies, testing materials, cleanup equipment, educational materials, transportation for volunteers, signs, basic monitoring equipment, or enough materials to test a conservation idea before trying to raise $20,000 for it.

For a newly formed ocean or environmental group, that is a perfectly reasonable place to begin.

4. Awesome Foundation Conservation & Climate

Deadlines: September 25 and November 27, 2026
Grant: $1,000

Official Conservation and Climate grant page

The Conservation and Climate chapter of the Awesome Foundation awards $1,000 microgrants to environmental projects involving areas such as wildlife conservation, habitat protection, climate, ecotourism, and environmental communication.

They openly encourage individuals and small teams to apply.

There is an important catch: they want ideas with some originality.

The chapter receives plenty of applications for tree planting, plastic cleanups, gardens, recycling, and similar projects. If your proposal is another beach cleanup, you need to explain what you are doing differently and why the $1,000 creates something useful beyond one cleanup day.

Citizen science, low-cost monitoring, an unusual conservation intervention, a prototype, or a new community stewardship method could make more sense here.

5. New England Grassroots Environment Fund Seed Grant

Deadline: Rolling
Grant: $500 to $1,000

Official Seed Grant page

For grassroots groups in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, this program deserves a bookmark.

Seed Grants provide $500 to $1,000 for newer community-led environmental initiatives. Applicants need at least two organizers actively involved in decision-making, but they do not need formal nonprofit status or a fiscal sponsor.

Its environmental areas include local land and water, which creates room for coastal stewardship, water protection, community science, pollution work, environmental justice, and similar local projects.

This is exactly the kind of grant small organizations should be looking for early on: reasonable amount, rolling application, and eligibility rules written with grassroots groups in mind.

6. Atherton Family Foundation

Deadline: October 1, 2026

Official Atherton Family Foundation grant page

The Atherton Family Foundation funds organizations in Hawaiʻi, with environment among its program areas.

The final 2026 program-request deadline is October 1 at 4:00 PM HST. Applications are submitted through the Hawaiʻi Community Foundation grants portal, and fiscal sponsorship is supported within the application process.

For Hawaiʻi nonprofits, the potential connection to ocean conservation is substantial: coastal stewardship, marine ecosystems, community conservation, climate resilience, reefs, watersheds, and environmental programs can all sit close to the foundation's geographic and environmental focus.

This application is more developed than a $500 grassroots grant, so have your organization budget and financial records in order before starting.

7. Florida Sea Turtle Grants Program

Deadline: November 6, 2026

Official Florida Sea Turtle Grants application page

Now we are unmistakably in ocean territory.

The Florida Sea Turtle Grants Program funds sea turtle conservation, research, and education benefiting Florida's marine turtles. The next proposal deadline is November 6, 2026 at 5 PM.

Organizations working on nesting beaches, turtle conservation, rehabilitation, monitoring, lighting issues, public education tied to turtle protection, or other direct marine-turtle work should review the program.

Pay attention to the application instructions here. The program requires the digital application and a signed original hard copy to meet its submission requirements, and projects requiring Marine Turtle Permits must have the necessary permit in place by the grant committee's specified stage.

This is specialized funding. If your actual work is sea turtles, specialized is exactly what you want.

8. Oregon Watershed Enhancement Board Small Grant Program

Applications accepted through April 15, 2027, subject to local team windows
Maximum request: $20,000
Match: 25%

Official Oregon Small Grant Program page

The Oregon Watershed Enhancement Board, or OWEB, provides grants of up to $20,000 for on-the-ground watershed restoration projects across Oregon.

Eligible applicants include not-for-profit corporations, watershed councils, tribes, schools, soil and water conservation districts, and other listed entities. Projects can address fish passage, stream conditions, erosion, riparian areas, water quality, and wildlife or watershed health.

For coastal organizations, watershed grants are easy to overlook because the title does not say ocean.

Salmon habitat, sediment, polluted runoff, degraded tributaries, erosion, and water quality are all connected to coastal ecosystems. If your marine mission includes protecting the systems feeding into the coast, this becomes highly relevant.

Applicants should contact their local Small Grant Team because application windows vary by area.

9. Ferris Olson Family Foundation for Ocean Stewardship

Deadline: October 12, 2026

Official FOFFOS grant application page

This one should probably be near the top of the reading list for an actual ocean organization.

The Ferris Olson Family Foundation for Ocean Stewardship, or FOFFOS, funds projects involving ocean and coastal conservation, ecosystem restoration and protection, advocacy, community stewardship, and marine animal rescue and rehabilitation.

Both established projects and pilot projects can qualify.

The foundation says previous requests have ranged from less than $10,000 to $50,000, with annual awards determined by available funding and the applications received. Applicants must be organizations recognized as 501(c)(3) by the IRS.

One thing to watch: the foundation wants action-oriented projects. Pure educational programming is not the focus, although education can be part of larger conservation work.

Recent grants have supported coral propagation and reef restoration, manatee conservation, and marine mussel monitoring for coastal health, which gives applicants a useful picture of the work they actually fund.

10. Chesapeake Bay Trust Community Engagement and Restoration Mini Grant

Deadline: Rolling
Maximum: $5,000

Official Community Engagement and Restoration Mini Grant page

This program is designed for community-level environmental projects in Maryland and the West Virginia portion of the Chesapeake Bay watershed.

Grants of up to $5,000 can support projects that engage community members or restore local natural resources. Match is encouraged but not required.

The program is especially worth noting for organizations newer to grant funding. Its eligibility rules explicitly encourage first-time applicants, and eligible applicants include nonprofits, faith-based groups, community associations, service groups, youth organizations, and public agencies.

For a small Chesapeake-area conservation organization, possibilities might include stream or shoreline stewardship, community restoration, native planting, cleanup work, or engagement tied directly to improving local natural resources.

11. Chesapeake Bay Trust Maintenance Small Grants

Deadline: Rolling until funds are exhausted
Maximum: $500

Official Maintenance Small Grants page

Here is a grant for the part of environmental work nobody photographs six months later: keeping the restoration alive.

The Maintenance Small Grants Program provides up to $500 for projects such as invasive-species control and replacing or improving plants at existing restoration sites. Applications remain open on a rolling basis until the year's funds are exhausted.

A $500 grant is obviously small.

So are plenty of maintenance problems until nobody deals with them.

If your organization already manages a rain garden, native planting, streamside project, or restoration site in Maryland, this could cover a very specific need without forcing you to build an entire new program just to justify funding.

12. Chesapeake Bay Trust Urban Trees Mini Grant

Deadline: Rolling
Maximum: $10,000

Official Urban Trees Mini Grant page

The Urban Trees Mini Grant supports tree planting in qualifying urban and underserved communities in Maryland, with requests up to $10,000. Nonprofits, community and homeowner associations, faith-based groups, and other eligible organizations may apply. Match is encouraged but not required.

Why is tree planting sitting inside an article about ocean conservation?

Because stormwater does not disappear after it leaves a parking lot.

Urban trees can help address runoff, flooding, erosion, and water quality problems that eventually affect rivers, estuaries, and coastal waters. For a nonprofit already working within that watershed relationship, the connection is legitimate.

If the only connection you can come up with is “trees are good for the planet and so are oceans,” leave this grant for somebody with a better project.

13. Chesapeake Bay Trust Watershed Assistance Grant Program

Deadline: December 9, 2026
Funding: Up to $150,000 depending on project type

Official Watershed Assistance Grant page

This is a larger program, but smaller nonprofits with a developed project should still know it exists.

The Watershed Assistance Grant Program supports watershed restoration design, permitting, planning, and program development in Maryland, qualifying portions of West Virginia, and specified watersheds in Pennsylvania.

Certain design projects, including wetland and marsh creation or restoration and living shorelines, can request up to approximately $150,000. Watershed planning and program-development projects generally request up to $75,000. Match is encouraged rather than required.

For a coastal nonprofit moving from community activities into a serious shoreline, wetland, or watershed project, funding for the planning and design stage can be extremely useful.

Just be realistic about capacity. Managing a six-figure technical grant is a different job from managing a $5,000 community project.

14. Keep Maryland Beautiful Grant Program

Deadline: December 1, 2026

Official Keep Maryland Beautiful grant page

Keep Maryland Beautiful supports community stewardship, land conservation capacity, and environmental projects throughout Maryland.

The Community Stewardship track offers requests of up to $5,000, while the Land Trust Assistance track allows requests up to $10,000. Match is encouraged but not required.

The community track is likely to be the more relevant one for a small environmental group working on stewardship, local environmental problems, education tied to action, planting, or volunteer engagement.

Applications close December 1, 2026 at 4 PM Eastern.

15. Clean Water Montgomery Grant Program

Deadline: November 13, 2026

Official Clean Water Montgomery grant page

The Clean Water Montgomery Grant Program funds watershed restoration and outreach work in Montgomery County, Maryland, with several considerably larger funding tracks.

Current limits include:

• Up to $40,000 for knowledge-building outreach projects

• Up to $60,000 for behavior-change projects

• Up to $100,000 for community-based restoration

• Up to $75,000 for water-quality monitoring

• Up to $50,000 for eligible litter-reduction projects in the Anacostia River watershed

Eligible applicants include 501(c)(3) nonprofits such as watershed groups, faith-based organizations, and civic organizations. The program also notes that organizations without current 501(c)(3) status may be able to work through a fiscal sponsor. Match is encouraged but not mandatory.

For an ocean or coastal nonprofit, the strongest connection is likely through water quality, litter entering waterways, monitoring, or restoration within the broader Chesapeake system.

Before You Apply to Any of These

A grant looking perfect from the title means very little. Read the eligibility section before you start writing.

For a small organization, check these first:

1. Location. Is your organization eligible, your project location eligible, or both?

2. Tax status. Does the funder require its own 501(c)(3), allow a fiscal sponsor, or accept informal groups?

3. Financial documents. What exactly will they ask you to upload?

4. Match requirement. Twenty-five percent match on a $20,000 award is a completely different financial decision from “match encouraged.”

5. Project type. Some funders want restoration. Some want advocacy. Some want education. Some explicitly refuse one of those.

6. Permits and property access. Restoration and wildlife projects may need approvals long before grant money arrives.

7. Restricted expenses. Check salaries, overhead, equipment, travel, lobbying, fundraising, and administrative expenses before building the budget.

8. Payment structure. Find out whether the grant is paid upfront or reimbursed after expenses.

And do this before polishing your project narrative. There is no prize for spending four hours writing a beautiful proposal before discovering your project is in the wrong county.

For small ocean nonprofits, the funding search usually needs to extend beyond grants carrying the word ocean. Marine-specific grants belong on the list, but so do watershed programs, wildlife funds, coastal restoration opportunities, local environmental grants, and small pilot-project funding. Follow the actual work your organization does, then follow where that work connects.
